Answer:

Explanation:

Solstice is gotten from the Latin word 'solstitium'. 'sol' means the sun and 'sistere' means 'to cause to stand or stand still'. From an astronomical point of view, this translation makes sense because this term is used to describe that particular instance when the sun attains its maximum northern point or maximum southern point from the equator of the earth.

When the sun attains northernmost point from the equator, summer solstice occurs and consequently causing the Earth to experience the longest day of the year. Similarly, when the sun attains its southernmost point from the equator, the Earth's proximity to the sun is at its closest and thereby making the Earth to experience the shortest day of the year. Astronomically, this is known as the winter solstice

Oksana_A [137]
Using the second Law of Newton, F = m * a, you know that acceleration is maximum when the force is maximum.


Using Hooke's Law, F = K Δx, you know that the force is maximum when the displacement from the equilibrium (Δx) is maximum.


So the answer is that the acceleration is maximum at the maximum amplitude x = a.

A railroad tank car contains milk and rolls at a constant speed along a level track. The milk begins to leak out the bottom. The
kifflom [539]

Answer:

option C

Explanation:

The correct answer is option C                        

There is no external force acting in the system hence the momentum will be conserved.                                    

As the milk is leaking out of the tank mass of the tanker is decreasing.

When the mass of the container will decrease to  conservation the momentum speed of the container will have to be increased.

So, the car carrying milk will speed up.

A 22 µF capacitor charged to 0.7 kV and a second 115 µF capacitor charged to 5.5 kV are connected to each other, with the positi
vesna_86 [32]

Answer:

0.099C

Explanation:

First, we need to get the common potential voltage using the formula

V=\frac {C_2V_2-C_1V_1}{C_1+C_2}

Where V is the common voltage, C and V represent capacitance and charge respectively. Subscripts 1 and 2 to represent the the first and second respectively. Substituting the above with the following given values then

C_1=22\times 10^{-6} F\\ C_2=115\times 10^{-6} F\\ V_1= 0.7\times 10^{3}\\V_2=5.5\times 10^{3}

Therefore

V=\frac {115\times 10^{-6}\times 5.5\times 10^{3}-22\times 10^{6}\times 0.7\times 10^{3}}{22\times 10^{-6}+115\times 10^{-6}}=4504.3795620437

Charge, Q is given by CV hence for the first capacitor charge will be Q_1=C_1V

Here, Q_1=22\times 10^{-6}\times 4504.3795620437=0.0990963503649C\approx 0.099C
